Carbon Capture in Molten Salts (CCMS) - Prototype

Carbon Capture in Molten Salts (CCMS) - Prototype

Heidi S. Nygård

CCMS is a high temperature method for extracting CO2 from a variety of flue gases related to power generation and carbon-intensive industries.



At REALTEK, an innovative high temperature CO2 capture concept has been developed since 2009; namely Carbon Capture in Molten Salts (CCMS). The method is based on similar principles as the Calcium Looping technology (CaL), but with the active substances (CaO/CaCO3) dissolved or partly dissolved in molten salts, allowing faster reaction kinetics, higher CO2 sorption capacity, and avoiding solids attrition issues. Through the terminated CLIMIT-FoU projects CCMS-I (Project 199900, 2010-2013) and CCMS-II (Project 233804, 2014-2018), a laboratory for high temperature molten salts research has been established. The CCMS concept has been validated for both absorption and desorption in a one chamber labscale reactor by bubbling simulated flue gases (0.76–15 vol% CO2 in N2) through various chloride and fluoride based melts, showing that the method is applicable for capturing CO2 from a variety of flue gases related to both energy intensive industry and power generation. 


More about the project

CCMS - Prototype (2020-2023) is continuation of the CCMS development, and the main aim of the project is to construct a two-chamber prototype reactor. Additionally, we will perform chemical characterization of the molten salt systems, evaluate and test construction materials suitable for the prototype, and investigate the effect of real flue gases on the sorption capacity. 

The project is coordinated by AGH University of Science and Technology (Poland), and funded by POLNOR CCS 2019 Call.

A Post Doc / researcher position will be announced at the NMBU web page in the near future. 

We also expect to have several topics for master theses during the project period. Previous master theses within CCMS are listed under "Publications".
